192 Driving and operating
After ignition is switched on, lane
keep assist is activated. If the system
is activated, the LED in the button Ó
is not illuminated . To activate the
system when the system is
deactivated, press Ó.
When the control indicator a in the
instrument cluster illuminates green,
the system is ready to assist.
The system is operational at vehicle
speeds between 65 km/h and
180 km/h and if lane markings are
available. The driver must hold the
wheel with both hands. The change of
trajectory is not accompanied by
operation of the direction indicators.
The ESC system must be activated.
The system makes the correction to
the trajectory necessary to return the
vehicle to its initial path if it identifies
a risk of the vehicle involuntarily
crossing one of the lane markings
detected. The driver will then notice a
turning movement of the steering
wheel.
The control indicator a flashes
during trajectory correction. In the
Driver Information Centre, the line of
the corrected side will be displayed in
orange.
If the driver wishes to maintain the
trajectory of the vehicle, he can
prevent the correction by keeping a
firm grip on the wheel (during an
avoiding manoeuvre, for example).
The correction is interrupted if the
direction indicators are operated.
While the direction indicators are on
and for a few seconds after switching
them off, the system considers that
any change of trajectory is voluntary
and no correction is triggered during
this period.
If the system detects that the driver is
not holding the wheel firmly enough
during an automatic correction of
trajectory, it interrupts the correction.
An alert is triggered to encourage the
driver to take back control of the
vehicle.
Deactivation
The system is deactivated by
pressing Ó during a few seconds; the
LED in the button illuminates. In the
Driver Information Centre, solid grey
lines are displayed.
